Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Glucose aus einem lignocellulosehaltigen Ausgangsmaterial, bei dem man dieses zunächst mit einer ionischen Flüssigkeit behandelt und anschließend einer enzymatischen Hydrolyse unterzieht. Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung von mikrobiellen Stoffwechselprodukten, speziell von Ethanol, bei dem man die erhaltene Glucose zusätzlich einer Fermentation unterzieht. The invention relates to a method for producing glucose from a starting material containing ligno-cellulose. According to said method, said material is initially treated with an ionic liquid and subsequently undergoes enzymatic hydrolysis. The invention also relates to a method for producing microbial metabolic products, especially ethanol, wherein the obtained glucose also undergoes fermentation. La présente invention concerne un procédé de production de glucose à partir d'une matière de départ contenant de la lignocellulose, ce procédé consistant dans un premier temps à traiter cette matière de départ au moyen d'un liquide ionique, puis à la soumettre à une hydrolyse enzymatique. L'invention concerne par ailleurs un procédé de production de métabolites microbiens, en particulier d'éthanol, ce procédé consistant à faire subir en outre une fermentation au glucose obtenu.
